Measurements of properties of the Higgs boson decaying into the four-lepton final state in pp collisions at √s=13 TeV

Abstract: Properties of the Higgs boson are measured in the H → ZZ → 4l (l = e, μ) decay channel. A data sample of proton-proton collisions at $ \sqrt{s}=13 $ TeV, collected with the CMS detector at the LHC and corresponding to an integrated luminosity of 35.9 fb$^{−1}$ is used. The signal strength modifier μ, defined as the ratio of the observed Higgs boson rate in the H → ZZ → 4l decay channel to the standard model expectation, is measured to be μ = 1.05$_{− 0.17}^{+ 0.19}$ at m$_{H}$ = 125.09 GeV, the combined ATLAS and CMS measurement of the Higgs boson mass. The signal strength modifiers for the individual Higgs boson production modes are also measured. The cross section in the fiducial phase space defined by the requirements on lepton kinematics and event topology is measured to be 2. 92$_{− 0.44}^{+ 0.48}$ (stat)$_{− 0.24}^{+ 0.28}$ (syst)fb, which is compatible with the standard model prediction of 2.76 ± 0.14 fb. Differential cross sections are reported as a function of the transverse momentum of the Higgs boson, the number of associated jets, and the transverse momentum of the leading associated jet. The Higgs boson mass is measured to be m$_{H}$ = 125.26 ± 0.21 GeV and the width is constrained using the on-shell invariant mass distribution to be Γ$_{H}$ < 1.10 GeV, at 95% confidence level.

A multiple-level model of evolution and its implications for sociobiology.

Abstract: The fundamental tenet of contemporary sociobiology, namely the assumption of a single process of evolution involving the selection of genes, is critically examined. An alternative multiple-level, multiple-process model of evolution is presented which posits that the primary process that operates via selection upon the genes cannot account for certain kinds of biological phenomena, especially complex, learned, social behaviours. The primary process has evolved subsidiary evolutionary levels and processes that act to bridge the gap between genes and these complex behaviours. The subsidiary levels are development, individual animal learning, and socioculture itself. It is argued that individual learning is pivotal to the derivation and biological analysis of culture. The differences between cultural and noncultural societies are stressed. It is concluded that such a multiple-level model of evolution can form the basis for reconciling opposing sides in the sociobiology debate.

Synchronization Control for A Class of Discrete Time-Delay Complex Dynamical Networks: A Dynamic Event-Triggered Approach

Abstract: This paper is concerned with the synchronization control problem for a class of discrete time-delay complex dynamical networks under a dynamic event-triggered mechanism. For the efficiency of energy utilization, we make the first attempt to introduce a dynamic event-triggering strategy into the design of synchronization controllers for complex dynamical networks. A new discrete-time version of the dynamic event-triggering mechanism is proposed in terms of the absolute errors between control input updates. By constructing an appropriate Lyapunov functional, the dynamics of each network node combined with the introduced event-triggering mechanism are first analyzed, and a sufficient condition is then provided under which the synchronization error dynamics is exponentially ultimately bounded. Subsequently, a set of the desired synchronization controllers is designed by solving a matrix inequality. Finally, a simulation example is provided to verify the effectiveness of the proposed dynamic event-triggered synchronization control scheme.

Corporate social responsibility and the social enterprise

Abstract: In this article, we contend that due to their size and emphasis upon addressing external social concerns, the corporate relationship between social enterprises, social awareness and action is more complex than whether or not these organisations engage in corporate social responsibility (CSR). This includes organisations that place less emphasis on CSR as well as other organisations that may be very proficient in CSR initiatives, but are less successful in recording practices. In this context, we identify a number of internal CSR markers that may be applied to measuring the extent to which internal CSR practices are being observed. These considerations may be contrasted with the evidence that community based CSR activities is often well developed in private sector small to medium sized enterprises (SMEs) (Observatory of European SMEs, 2002), a situation which may be replicated in social enterprises especially those that have grown from micro-enterprises embedded in local communities. We place particular emphasis upon the implications for employee management. Underpinning our position is the Aristotelian-informed capabilities approach, a theory of human development and quality of life, developed by Sen (1992; 1999) and Nussbaum (1999) which has been developed further, in an organisational context, (e.g., Cornelius, 2002); Cornelius and Gagnon, 2004; Gagnon and Cornelius, 1999; Vogt, 2005. We contend that the capabilities approach offers additional insights into CSR in social enterprises in general and internal CSR activity in particular. Our article concludes with proposals for future research initiatives and reflections upon social enterprise development from a capabilities perspective.
